KBS Coatings DiamondFinish Clear, 5 gal.

The 5 gallon pail of KBS DiamondFinish Clear is the shop size, for farm and fleet shops clearing tractor sheet metal, aluminum trailer diamond plate, gooseneck and stock trailers, toolboxes, brush guards, and exhaust stacks. It is a single component moisture cured urethane, so there is no hardener to mix and no catalyst to buy. Stir it and go. It flows out water clear over fresh paint, polished aluminum, chrome, stainless, and fiberglass, and it stays clear instead of going amber after a season in the field. It reaches 7H pencil hardness in 7 days, takes a 160 inch pound impact, and has run 1000 hours of salt spray. It shrugs off diesel, fertilizer, battery acid, and most every solvent, and it is rated to 325 degrees Fahrenheit without yellowing. Brush, roll, or spray it, then cut and buff after 24 hours. A pail covers about 2000 sq ft per coat at 2 mils. It is UV stable but does not block UV, so the color under it must be UV stable in full sun. Made in the USA.Prep is what makes a clear coat last. Over a cured automotive base coat, let the color dry about an hour and go straight over it. Over older cured coatings, wash with KBS Klean diluted 10 parts hot water to 1 part cleaner, scuff with 600 to 1200 grit, clean again, rinse, and dry. On bare ferrous metal, sand or polish to the finish you want, then clean at that same 10 to 1 dilution. On aluminum, brass, or copper, use 25 parts hot water to 1 part KBS Klean, wipe rather than soak, and rinse right away. Never use a solvent rag or a tack cloth, since the residue causes fisheyes. Apply between 50 and 82 degrees Fahrenheit in moderate to dry air. Do not shake the can. Stir thoroughly, pour a working amount into a clean steel or glass container, and reseal the can. Apply at least 2 thin coats at 2 mils each, or 3 for marine and industrial work. Thin 10 to 15 percent with KBS number 1 Thinner or xylene when spraying, never lacquer thinner. Recoat in 2 to 4 hours. Clean tools right away.
